CompTIA Linux+ (XK0-004) — Question 27

Which of the following configuration files should be modified to disable Ctrl+Alt+Del in Linux?

Answer options

• A. /etc/inittab
• B. ~/.bash_profile
• C. /etc/securetty
• D. /etc/security/limits.conf

Correct answer: A

Explanation

The correct answer is A, as the /etc/inittab file is responsible for defining the actions for the Ctrl+Alt+Del key combination in Linux. The other options do not control this functionality; ~/.bash_profile is for user-specific environment settings, /etc/securetty restricts root login, and /etc/security/limits.conf sets user resource limits.
